NOTE:
If your modem is not listed and/or you do not see a series of
commands and responses, make sure that your cables are attached
correctly to your computer. If your modem still does not work, refer to
the additional troubleshooting section of this guide. Shut down and restart your
computer. To verify that your modem is functioning properly, repeat the steps
listed for your operating system.
For additional troubleshooting help, review these common
issues:
My computer isn't recognizing my modem.
Possible solution: You may be using a COM port that is either already in use
or not configured correctly. For the modem to work properly, it must be
plugged into an enabled serial port which is assigned to a free COM port.
Most computers have two serial ports assigned to COM 1 and COM 2
respectively.
Windows XP, 2000
Make sure your COM port is not already in use by another modem. Click
Windows Start, Settings (for Windows 2000 only), and Control Panel, and
then double-click Phone and Modem Options. Click the Modems tab. Look
for a listed modem and check which COM port it is using. If a previous
modem is already using the available COM port, you can either use another
COM port or uninstall the modem that was installed previously. See your
previous modem's manual for uninstallation instructions. Next make sure
that your COM ports are configured correctly. Right-click the My Computer
icon on your desktop. Click Properties. Click the Hardware tab. In the
"Device Manager" section, click the Device Manager button. Look under
Ports (COM and LPT). If the Communications ports have yellow exclamation
points or red Xs over them, your COM ports may be configured incorrectly.
If this is the case, you may need to contact your computer manufacturer. It
is also possible that you may be plugging your external modem's cable into
a disabled serial port. Refer to your computer's manual for information
about enabling COM ports. This usually involves altering the BIOS settings
and possibly the operating system. You may need to call your computer's
manufacturer to change your BIOS settings if they are incorrect.
Windows Me, 98, 95
Make sure your COM port is not already in use by another modem. Click
Windows Start, Settings, and Control Panel, and then double-click
Modems. If you have Windows Me and you do not see this icon, be sure to
select View All Control Panel Options. Look for another modem listed and
if another modem is listed, click the Diagnostics tab to find out which COM
